Abstract:
Data on tsunami damaged houses, collected and compiled by the Department of Census and Statistics, Sri Lanka, was used to construct vulnerability curves with tsunami height as the demand parameter. A common curve could be used for all administrative divisions where a majority of houses had permanent walling materials, whether these divisions were on the southwest coast or the north and east coast. A Monte Carlo simulation was carried out for a typical building using varying tsunami inundation depths, and the
resulting vulnerability curve was found to be similar, but lie just below, the survey-based curve, because all the buildings used for the simulated curve had permanent walling materials. This paper focuses only on the ‘complete damage’ state for vulnerability.
